Authentic asMODus VR Oni Ignition Pod Kit - $29.99
1.5ohm pods, 1.8ml capacity. 500mah internal battery. It really does just look like a key fob for your car. Not sure who they're targeting with that look, but it could definitely be discrete on a keychain.

EVL Reaper V3 Styled MTL RTA - $20.95
22mm, 2/5ml capacity, 316SS. Comes with 2 different tank/chimney sections for 2ml or 5ml capacity. Also included are 2 AFC rings, one flush and on flared depending on what look you are going for. It's unfortunate that the deck is just a 2 post design where you capture the coil legs under the screws.

YFTK KA V8 Styled RTA - $21.79
22mm, 5ml capacity, 316SS. The deck/AFC section of this seems way oversized, especially considering they aren't doing anything special with the airflow to the coil. 5ml capacity is nice though, and it's still only listed as 61mm tall (excluding drip tip I would assume)

First off, this guy looks like a total badass in this picture. Second off, the 4th picture shows bullets coming at it and "High Inpact Resistance, Make You Safer". Come on now. This isn't going to stop bullets, airsoft yes, but not bullets. But it doesn't even cover the eyes, so you need some goggles to even make it good for that.
